ʻO ke kumu o nā mea kanu asphalt ka hana ʻana i ka asphalt mix wela. Hoʻohana kēia mau mea kanu i nā ʻāpana, ke one, ka bitumen a me nā mea ʻē aʻe e hana ai i ka asphalt, i kapa ʻia ʻo blacktop a i ʻole asphalt concrete.
ʻO ka hana nui o kahi mea kanu hui asphalt, ʻo ia ka hoʻomaʻamaʻa ʻana i nā aggregates a laila hui pū me ka bitumen a me nā mea hoʻopili ʻē aʻe e hoʻoulu ai i ka asphalt mix wela. ʻO ka nui a me ke ʻano o ka hui e pili ana i nā koi kikoʻī. Hiki iā ia ke hoʻokahi mea nui a i ʻole ka hui pū ʻana o nā mea he nui o nā ʻano like ʻole, me ka hui pū ʻana o nā ʻāpana maikaʻi a me nā ʻāpana.
Nā ʻano mea kanu Asphalt
ʻO ka hana ʻana o nā mea kanu asphalt ma muli o ke ʻano o nā mea kanu asphalt. ʻO ka maʻamau, ʻelua ʻano nui o nā mea kanu asphalt. ʻO ke kumu kumu o kēia mau ʻano a pau e hana i ka asphalt huikau wela. Eia nō naʻe, aia nā ʻokoʻa koʻikoʻi ma waena o kēia mau mea kanu e pili ana i ke ala e loaʻa ai nā hopena i makemake ʻia a ma nā hana hana holoʻokoʻa.
1. Hui Hui Pūʻali
Aia kekahi mau mea i komo i loko o kahi mea kanu hui pū me ka asphalt concrete. ʻO kekahi o nā mea koʻikoʻi e pili ana i ia mau mea kanu, ʻo ia ka hoʻohana ʻana i nā pahu hānai hui anuanu no ka mālama ʻana a hānai i nā mea kanu i nā ʻāpana like ʻole e like me ko lākou nui. Eia kekahi, loaʻa iā lākou kahi kāʻei hānai kōkua ma lalo o kēlā me kēia pahu.
Hoʻohana ʻia ka conveyor e hoʻololi i nā aggregates mai kekahi conveyor i kekahi. ʻO ka hope, hoʻoili ʻia nā mea a pau i ka pahu maloʻo. Eia nō naʻe, pono e hele nā aggregates i ka pale vibrating e hōʻoia i ka wehe pono ʻana o nā mea nui.
ʻO ka pahu hoʻomaloʻo he ʻāpana puhi ahi e hoʻoneʻe i ka makū a hoʻomehana i nā aggregates e hōʻoia i kahi mahana hui maikaʻi loa. Hoʻohana ʻia ka ʻeleke no ka lawe ʻana i nā aggregates i luna o ka hale kiaʻi. ʻEkolu mau ʻāpana nui o ka hale kiaʻi: ʻo ka pale haʻalulu, nā pahu wela a me ka hui hui. Ke hoʻokaʻawale ʻia nā aggregates e ka pale vibrating e like me ko lākou nui, mālama ʻia lākou i kahi manawa i loko o nā keʻena like ʻole i kapa ʻia ʻo hot bins.
Hoʻopaʻa nā pahu wela i ka hui i loko o nā pahu ʻokoʻa no kekahi manawa a laila hoʻokuʻu iā lākou i loko o ka hui hui. Ke kaupaona ʻia nā mea hōʻuluʻulu a hoʻokuʻu ʻia, hoʻokuʻu pinepine ʻia ka bitumen a me nā mea pono ʻē aʻe i loko o ka hui hui pū kekahi.
Ma ka hapa nui o nā ʻoihana ʻoihana, pono ka hoʻokomo ʻana i nā mea hoʻomalu i ka hoʻohaumia ʻana i ka ea e hōʻoia i ka hoʻomau ʻana a me ka ʻoluʻolu o nā mea kanu asphalt. ʻO ka maʻamau, hoʻohana ʻia nā ʻāpana kānana ʻeke e paʻa i nā ʻāpana lepo. Hoʻohana pinepine ʻia ka lepo i loko o ka elevator aggregate.
2. Mea kanu hui pahu
Nui nā ʻano like o nā mea kanu asphalt drum mix me nā mea kanu hui batch. Hoʻohana ʻia nā pahu anu i nā mea kanu pahu pahu. Eia kekahi, ua like ke kaʻina hana me ka mea kanu hui a hiki i ke komo ʻana o nā aggregates i ka pahu ma hope o ka hele ʻana i ka pale vibrating e hoʻokaʻawale iā lākou ma ke kumu o ko lākou nui.
ʻElua mau hana nui o ka dram: ka maloʻo a me ka hui ʻana. Hoʻohana ʻia ka ʻāpana mua o ka pahu e hoʻomehana i nā aggregates. ʻO ka lua, ua hui pū ʻia nā aggregates me ka bitumen a me nā mea kānana ʻē aʻe. He mea nui e hoʻomaopopo i ka pahu hui asphalt mea kanu he mea hoʻohui mau. No laila, hoʻohana ʻia nā ipu liʻiliʻi a i ʻole kahi mea kūpono e hoʻopaʻa ai i ka asphalt mix wela.
No ka hui ʻana o ka bitumen ma hope o ka hana ʻana, mālama mua ʻia i loko o nā pahu kaʻawale a laila hoʻokomo ʻia i loko o ka lua o ka pahu. He mea nui ka mālama ʻana i ka maikaʻi o ka ea i mea e pale aku ai i ka pollution. No kēia kumu, hoʻohana maʻamau nā mea hoʻomalu pollution e like me nā ʻōpala pulu a i ʻole nā kānana ʻeke i nā mea kanu asphalt mix drum.
ʻIke ʻia ʻo kēia mau ʻano mea kanu ʻelua kekahi mau mea maʻamau a me nā kaʻina hana. No ka laʻana, pono nā pahu hānai i nā mea kanu ʻelua a me nā mea kanu mau. Pēlā nō, he mea nui ka pale vibrating i kēlā me kēia ʻano mea kanu asphalt. ʻO nā ʻāpana ʻē aʻe o nā mea kanu e like me nā mea hoʻokiʻekiʻe bākeke, hui pū ʻana e like me nā pahu, nā hoppers kaupaona, nā pahu mālama, nā kānana ʻeke a me nā keʻena hoʻomalu he mea nui hoʻi i nā mea kanu hui pū a me nā mea kanu pahu pahu.
ʻO ke kumu o ka hoʻokaʻawale ʻana ma waena o kēia mau ʻano mea kanu asphalt nui ʻelua, ʻo ia ka hōʻike ʻana i nā ʻano mea kanu ʻelua e hoʻopuka i nā asphalt mix wela maikaʻi, ʻoiai inā hoʻohana lākou i nā ʻōnaehana hana like ʻole.
ʻO ke ʻano o ka mea kanu asphalt a kahi hui e makemake ai e hoʻokumu e hilinaʻi nui ʻia i kā lākou mau koi ʻoihana, kālā a me nā lula āpau a me nā hoʻoponopono o ka wahi ʻoihana. No ka 'ike hou aku
Hōʻuluʻulu manaʻo
Hoʻokumu nā mea kanu asphalt i ka asphalt hui pū me ka hoʻohana ʻana i nā aggregates, one, bitumen, a me nā mea ʻē aʻe. ʻO ke kaʻina hana ʻo ia ka hoʻomehana ʻana i nā aggregates a hui pū me ka bitumen e hana i ka asphalt. ʻElua ʻano nui o nā mea kanu asphalt: hui pū a hui pahu.
Hoʻokumu nā mea kanu hui hui i ka asphalt i nā pūʻulu, me ka hoʻohana ʻana i kahi kaʻina hana he nui e pili ana i nā mea hānai huʻihuʻi, nā pale haʻalulu, a me nā ʻāpana hui. ʻO nā mea kanu pahu pahu, ma kekahi ʻaoʻao, e hana mau ana, e hui pū ana i ka maloʻo a me ka hui ʻana i hoʻokahi pahu. Hāʻawi nā ʻano mea kanu ʻelua i ka asphalt kiʻekiʻe, me ke koho e pili ana i nā pono ʻoihana, kālā, a me nā lula.
